Sometimes they are grouped as dabbling ducks, diving ducks and sea ducks. There are other groups as well. If you mean domestic ducks, they are mostly descended from mallard ducks. They are omnivores. They eat about 1/3 animal and 2/3 plant matter. The animals they eat are gastropods, invertebrates (including beetles, flies, lepidopterans, dragonflies, and caddisflies), crustaceans, worms and sometimes frogs. They feed by dabbling, grazing and hunting for invertebrates on land and in the water.
